Lolobau volcano sits astride the western rim of a 6-km-wide caldera, which formed about 12,000 years ago. The 8 x 13 km, oval-shaped Lolobau Island is located just off the coast of eastern New Britain. A small lake occupies the SW part of the caldera. A small lava dome (Hulu) caps Mount Lolobau, which has a 0.8 x 1.1 km summit crater that is breached to the NE. Flank cones are found along the coast of the largely submerged volcano. Several vents within the caldera along an E-W-trending line on the eastern flank of Mount Lolobau have been active during historical time. The latest eruptions took place during the early-20th century.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Lolobau volcano (left) sits astride the western rim of a caldera that formed about 12,000 years ago on the 8 x 13 km, oval-shaped Lolobau Island. It is seen here from the south across Expectation Strait along the NE coast of New Britain. The peak at the right lies on the eastern rim of the 6-km-wide caldera. Several vents within the caldera, occupying an E-W-trending line on the eastern flank of Mount Lolobau, have been active during historical time.

The oval-shaped island of Lolobau lies just off the northern coast of New Britain, west of Cape Deschamp. Lolobau was constructed over the western rim of a 6-km-wide caldera. Eruptive activity from vents on the flank of Lolobau inside the caldera have continued into the 20th century.

Lolobau volcano (left center) sits astride the western rim of a 6-km-wide caldera, which formed about 12,000 years ago on the 8 x 13 km, oval-shaped Lolobau Island. Lolobau is seen here from the south beyond the lower flanks of Ulawun volcano. The smaller peak at the right is located along the eastern caldera rim. Several vents within the caldera along an E-W-trending line on the eastern flank of Mount Lolobau have been active during historical time. The latest eruptions took place during the early-20th century.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.
